Former Liverpool and Manchester City star Didi Hamann has questioned Arsenal's move for FC Cologne star Lukas Podolski. Reports this week suggested terms have been agreed between all parties over a summer transfer.

Hamann told talkSPORT: "Podolski is obviously a very good player because he has shown it for a number of years in the [German] national team. He's scored a lot of goals for them but the only thing is that most of his form, or all of his best form, is in the national team.

"He went to Bayern Munich a few years ago, he couldn't really make a breakthrough there, and obviously he's back in his home town of Köln where he is loved, where he's their main player and he blossoms.

"He's scored a lot of goals this year but again, the one time he played for a big club, at Bayern, he didn't really cut it.

"It's always different to play at a big club because you're one of many and at Köln he's their main player. He's scored more goals this season than the rest of the team [combined]."
